## Abstract We present calculations of indirect nuclear spin–spin coupling constants in large molecular systems, performed using density functional theory. Such calculations, which have become possible because of the use of linear‐scaling techniques in the evaluation of the Coulomb and exchange‐cor
The linewidths of 10 B NMR signals of tetrachlorotetraborane (1), measured at various temperatures, indicate that there are weak scalar 11 B-10 B interactions. Selective homonuclear 11 Bf 11 Bg decoupling experiments confirmed previous signal assignments and improved the resolution of 11 B NMR spect
Tetrakis(trimethylstannyl) germanium was prepared and studied by 1 H, 13 C, 73 Ge and 119 Sn NMR spectroscopy. Quadrupolar relaxation of the 73 Ge nucleus is slow, which allows one to measure 1 J 117/119 Sn, 73 Ge D 37 Hz and to determine its positive sign by a 2D heteronuclear 73 Ge-1 H shift corr
## Abstract As the magnetic fields used in NMR spectrometers become greater, it is expected that a field dependence of nuclear spin–spin coupling will be observed. A part of this, which would be independent of temperature, is due to the contributions of higher terms in the Hamiltonian of the molecu
